Propellants, Explosives, Pyrotechnics, EarlyView.Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...

Mixed finite element models for free vibrations of thin-walled beams [PDF]
Simple, mixed finite element models are developed for the free vibration analysis of curved thin-walled beams with arbitrary open cross section. The analytical formulation is based on a Vlasov's type thin-walled beam theory with the effects of flexural ...

Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications
Packaging Technology and Science, EarlyView.Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and
